What does the neuron's Myelin Sheath do?
Controls the actions of the neuron
Produces food for the neuron
Carries information from the cell body to other neurons
Surrounds and insulates the axon
What do Dendrites do?
Receives information from other neurons via neurotransmitters
Produces fatty tissue for the Myelin Sheath
Sends information to the next cell
Controls the speed of electrical signal through the axon
What do Axon Terminals do?
Receives information from other neurons
Produces fatty tissue for the Myelin Sheath
Sends information to the next cell
Controls the speed of electrical signal through the axon
